BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a sliding bracket device for a guide motor, and more specifically, to a sliding bracket device for a guide motor that is capable of allowing a slide frame part to slide on a fixed frame part so that the guide motor disposed on top of the slide frame part is selectively located inside and outside a boat according to the sliding directions of the slide frame part.

Background of the Related Art

Generally, a bracket is used to fixedly connect a device to a specific position such as a wall, a ceiling, and the like, and the bracket may be made of different materials in different shapes according to the types of devices to be fixed and the fixed positions of the devices.

Further, a guide motor is a device for supplying a force to a boat that converts energy into power to provide a propulsion force for the boat, so that the boat moves to a desired position or the boat moving to the desired position is fixed to the corresponding position.

The guide motor is used to move the boat to the desired position, but usually, it is used to fix the boat moving to the desired position to the corresponding position. In this case, the guide motor is used in a state of being disposed to protrude outward from the boat.

In the case where the guide motor is used in the state of being disposed to protrude outward from the boat, however, the guide motor protruding outward from the boat may collide against an obstacle or the like at the time when the boat moves, so that the guide motor may be damaged or broken.

One of conventional technologies related to the bracket is disclosed in Korean Patent No. 10-0713772 entitled ‘Slide type variable mounting bracket’.

The conventional slide type variable mounting bracket is fixed to a wall body of a building to mount an electronic device or part such as a radio repeater and the like on top thereof and configured to have a mounting part easily variable if necessary, and the mounting bracket includes a slide bracket with the same shape as top of a mounting bracket body, disposed appearingly/disappearingly inside the mounting bracket body, and having guide rails located on the underside thereof correspondingly to guide rails disposed on top and underside of the interior of the mounting bracket body to move the guide rails of the mounting bracket body.

According to the conventional mounting bracket, the slide bracket, which performs sliding movements, appears and disappears from the mounting bracket body, but in a state where a given device is fixed to the slide bracket, it is impossible to slide the slide bracket.

The present invention relates to a sliding bracket device for a guide motor that is capable of allowing a slide frame part to slide on a fixed frame part so that the guide motor disposed on top of the slide frame part is selectively located inside and outside a boat according to the sliding directions of the slide frame part.

Hereinafter, an explanation of a sliding bracket device for a guide motor according to the present invention will be given in detail with reference to the attached drawings.

FIGS. 1A and 1B are perspective views showing a sliding bracket device for a guide motor according to the present invention, FIGS. 2A and 2B are top views showing operating states of the sliding bracket device for a guide motor according to the present invention, and FIGS. 3A and 3B are top views showing states in which the sliding bracket device for a guide motor according to the present invention really operates.

Referring to FIGS. 1A to 3B, a sliding bracket device for a guide motor according to the present invention largely includes a fixed frame part 100 and a slide frame part 200.

The sliding bracket device for a guide motor according to the present invention is installed on the bow or stern of a boat 10 to connect the guide motor 20 to the boat 10, and in a state where the guide motor 20 is located on the slide frame part 200, the slide frame part 200 slides on the fixed frame part 100 by a user's control.

Accordingly, the fixed frame part 100 is installed on the bow or stern of the boat 10.

In specific, the fixed frame part 100 is installed on the bow or stern of the boat 10, on which the slide frame part 200 as will be discussed later slides, so that the fixed frame part 100 is coupled to the boat 10, without any shaking, to allow the slide frame part 200 to easily slide thereon in a state where the slide frame part 200 is disposed thereon.

The fixed frame part 100 has the shape of a rectangle, but according to embodiments of the present invention, the fixed frame part 100 may be freely changed in shape only if the slide frame part 200 disposed on top thereof easily slides thereon.

The slide frame part 200 is disposed to slide on top of the fixed frame part 100 and configured to install the guide motor 20 thereon.

In the case where the slide frame part 200 slides in one side direction thereof, it is configured to allow the guide motor 20 to be located inside the boat 10, and contrarily, in the case where the slide frame part 200 slides in the other side direction thereof, it is configured to allow the guide motor 20 to be located outside the boat 10.

In specific, the slide frame part 200 slides on top of the fixed frame part 100 according to the user's control, so that the guide motor 20 installed on the slide frame part 200 is selectively located inside and outside the boat 10.

Further, the slide frame part 200 includes a pair of guide members 210 coupled to the undersides of both sides thereof to extend in a direction toward the fixed frame part 100, and the fixed frame part 100 includes a plurality of shafts 110 coupled to top thereof in a direction perpendicular thereto and guide rollers 120 rotatably coupled to the outer peripheral surfaces of the shafts 110, respectively, to the shapes coming into contact with the guide members 210 so that if the slide frame part 200 slides, the guide rollers 120 rotate around the shafts 110 by means of the guide members 210.

If the slide frame part 200 slides, that is, the guide members 210 of the slide frame part 200 come into contact with the guide rollers 120 and thus slide together with the slide frame part 200, and accordingly, the guide rollers 120 rotate by means of the sliding movements of the guide members 210 to guide the sliding movements of the guide members 210.

In this case, each guide member 210 has the shape of a rod with a circular section, and the guide rollers 120 whose surfaces coming into contact with the guide members 210 have the corresponding shapes to the shapes of the guide members 210, so that the guide rollers 120 rotate by means of the sliding movements of the guide members 210, while inserting portions of the guide members 210 thereinto.

In more specific, the guide rollers 120 whose surfaces coming into contact with the guide members 210 have the corresponding shapes to the circular shapes of the guide members 210, and when the surfaces of the guide rollers 120 coming contact with the guide members 210 extend to have imaginary circular shapes, diameters of the imaginary circular shapes are larger than the diameters of the circular shapes of the guide members 210, so that an excessive force needed when excessive contacts occur between the guide rollers 120 and the guide members 210 is not required for the sliding movements of the guide members 210.

Like this, four shafts 110 and four guide rollers 120 are needed to guide the sliding movements of one pair of guide members 210, and they are disposed on the corners of top of the fixed frame part 100.

Further, the slide frame part 200 includes connection members 220 disposed on one end and the other end of the guide members 210 to connect the guide members 210 to each other, thereby preventing a distance between the guide members 210 from being varied, and the connection members 220 have stoppers 221 adapted to limit the sliding distances of the slide frame part 200 during the sliding movements of the slide frame part 200.

The connection members 220 connect the pair of guide members 210 to each other to prevent the distance between the guide members 210 from being varied, so that while the guide members 210 are sliding, they are easily guided by means of the guide rollers 120.

The stoppers 221 extend from the connection members 220 toward the fixed frame part 100 to cover at least portions of the fixed frame part 100.

In specific, the stoppers 221 are locked onto the fixed frame part 100 to limit the moving distance of the slide frame part 200 during the sliding movements of the slide frame part 200.

For example, if the slide frame part 200 slides in one side direction thereof, the stoppers 221 of the connection members 220 are locked onto the other side of the fixed frame part 100 to limit the sliding movement of the slide frame part 200, and if the slide frame part 200 slides in the other side direction thereof, the stoppers 221 of the connection members 220 are locked onto one side of the fixed frame part 100 to limit the sliding movement of the slide frame part 200.

Further, each guide member 210 has one or more slide fixing grooves 211 formed thereon in a longitudinal direction thereof, and the fixed frame part 100 includes extension portions 130 protruding therefrom to cover at least portions of the guide members 210, through holes 140 formed on the extension portions 130, and slide fixing pins 150 inserted into the through holes 140 and the slide fixing grooves 211 to prevent the sliding movements of the guide members 210.

That is, the slide fixing pins 150 pass through the through holes 140 of the extension portions 130 and the sliding fixing grooves 211 to prevent the guide members 210 from sliding, and according to the positions of the slide fixing grooves 211 formed on the guide members 210, the fixed positions of the guide members 210 are determined.

For example, the slide fixing grooves 211 are formed on one side ends of the guide members 210, and if the slide frame part 200 slides in the other side direction thereof, the slide fixing pins 150 are inserted into the slide fixing grooves 211 so that the guide members 210 are fixed in position. Further, the slide fixing grooves 211 are formed on the middle portions of the guide members 210, and if the slide frame part 200 slides in one side direction thereof, the slide fixing pins 150 are inserted into the slide fixing grooves 211 so that the guide members 210 are fixed in position.

According to the present invention, the two slide fixing grooves 211 are formed on the guide members 210, respectively, and if the slide frame part 200 slides in one side and the other side direction thereof, the slide fixing pins 150 are inserted into the slide fixing grooves 211. According to embodiments of the present invention, however, two or more slide fixing grooves 211 may be formed on the guide members 210, respectively, and accordingly, the guide motor 20 may be freely set in position according to the sliding movements of the guide members 210.

Further, the slide fixing pins 150, which are inserted into the through holes 140 of the extension portions 130 and the slide fixing grooves 211 of the guide members 210, apply elastic forces in directions where the through holes 140 and the slide fixing grooves 211 are formed, and if the through holes 140 and the slide fixing grooves 211 are concentric with each other according to the sliding movements of the guide members 210, accordingly, the slide fixing pins 150 are automatically inserted into the through holes 140 and the slide fixing grooves 211.

In specific, the slide fixing pins 150 always move in the directions where the through holes 140 and the slide fixing grooves 211 are formed by means of the elastic forces, and if it is desired to slide the slide frame part 200, accordingly, the slide fixing pins 150 initially escape from the through holes 140 and the slide fixing grooves 211. After the slide frame part 200 slides, even though the slide fixing pins 150 are released from the user's hands, they are not inserted into the through holes 140 and the slide fixing grooves 211 if the slide frame part 200 does not slide to a pre-determined position, so that it is easy to control the slide fixing pins 150.

For example, if it is desired to slide the slide frame part 200, the slide frame part 200 slides in the state where the sliding fixing pins 150 initially escape from the through holes 140 and the slide fixing grooves 211, and in this case, even though the slide fixing pins 150 are released from the user's hands, they are in a stand-by state until the slide frame part 200 slides to a desired position. After that, if the slide frame part 200 slides to the desired position, the slide fixing pins 150 are inserted into the slide fixing grooves 211 of the guide members 210, respectively, by means of their elastic force.

FIGS. 4A and 4B are perspective views showing a rotation part of the sliding bracket device for the guide motor according to the present invention, and FIGS. 5A to 5C are top views showing operating states of the rotation part of the sliding bracket device for the guide motor according to the present invention.

Referring to FIGS. 4A to 5C, the sliding bracket device for the guide motor according to the present invention further includes a rotation part 300 disposed between the bow or stern of the boat 10 and the fixed frame part 100 to allow the fixed frame part 100 to be rotatable around the bow or stern of the boat 10.

That is, the rotation part 300 is configured to rotate the fixed frame part 100 to allow the guide motor 20 disposed on the slide frame part 200 to rotate, and according to embodiments of the present invention, the rotation part 300 may be applied to various environments.

The rotation part 300 includes a fixed plate 310 disposed between the bow or stern of the boat 10 and the fixed frame part 100, a rotating shaft 320 whose one side is fitted to the fixed plate 310 and the other side is fitted to the fixed frame part 100 to allow the fixed frame part 100 to rotate with respect to the fixed plate 310, and a rotation fixing pin 330 adapted to pass through the fixed frame part 100 and the fixed plate 310 to fix the rotation of the fixed frame part 100.

The fixed plate 310 is fixed to the bow or stern of the boat 10 to allow the fixed frame part 100 to stably rotate.

The fixed plate 310 has brackets 313 extending downward therefrom, and as the brackets 313 are coupled to the bow or stern of the boat 10, the fixed plate 310 is easily installed on the bow or stern of the boat 10.

The rotating shaft 320 serves to easily rotate the fixed frame part 100 located on top of the fixed plate 310.

The rotation fixing pin 330 passes through the fixed plate 310 and the fixed frame part 100 rotating around the rotating shaft 320, so that the fixed plate 310 and the fixed frame part 100 are connected to each other by means of the rotating shaft 320 and the rotation fixing pin 330, thereby preventing the fixed frame part 100 from rotating to thus fix the fixed frame part 100 in position.

Further, the fixed plate 310 has a plurality of fixing holes 312 formed thereon in a circumferential direction with respect to a position where one side of the rotating shaft 320 is located, and the fixed frame part 100 has a first through hole 160 formed at a position corresponding to any one of the plurality of fixing holes 312. According to up and down movements of the rotation fixing pin 330, the rotation fixing pin 330 passes through the first through hole 160 of the fixed frame part 100 and any one of the plurality of fixing holes 312 of the fixed plate 310 and thus fixes the rotation of the fixed frame part 100 with respect to the fixed plate 310.

In specific, the rotation fixing pin 330, which is adapted to pass through the fixed frame part 100 and the fixed plate 310 to fix the rotation of the fixed frame part 100, is inserted into any one of the plurality of fixing holes 312 and the first through hole 160, so that the fixed frame part 100 rotates to a desired angle by the user and is then fixed.

The fixed frame part 100 is configured to rotate by an angle formed by the plurality of fixing holes 312 of the fixed plate 310, and according to embodiments of the present invention, the fixed frame part 100 can rotate by an angle of 45° in left and right directions. The plurality of fixing holes 312 are spaced apart from one another by intervals of 5 to 10°, thereby enabling the rotating angle of the fixed frame part 100 to be precisely controlled.

In this case, the rotation fixing pin 330, which is adapted to pass through the fixed frame part 100 and the fixed plate 310, applies an elastic force in a direction where the fixing holes 312 and the first through hole 160 are formed, that is, in a downward direction, like the slide fixing pins 150, and if any one of the fixing holes 312 and the first through hole 160 are concentric with each other according to the rotation of the fixed frame part 100, accordingly, the rotation fixing pin 330 is automatically inserted into any one of the fixing holes 312 and the first through hole 160.

Further, the fixed frame part 100 includes a plurality of guide pin holes 170 extending in a circumferential direction around a position where the other side of the rotating shaft 320 is located, and the fixed plate 310 has a plurality of second through holes 311 formed at the positions corresponding to the plurality of guide pin holes 170. The rotation part 300 includes guide pins 340 adapted to guide the rotation of the fixed frame part 100 upon the rotation of the fixed frame part 100, and each guide pin 340 has one side disposed on the corresponding second through hole 311 of the fixed plate 310 and the other side disposed on the corresponding guide pin hole 170 of the fixed frame part 100.

In specific, the sliding bracket device for the guide motor according to the present invention is configured to allow each guide pin 340 to be disposed on any one of the plurality of guide pin holes 170 and the second through hole 311, and as the fixed frame part 100 rotates, the guide pins 340 slide along the extending shapes of the guide pin holes 170 to guide the rotation of the fixed frame part 100.

In more specific, in a state where one side of the guide pin 340 is fixed to the second through hole 311 of the fixed plate 310, the other side of the guide pin 340 is disposed in the guide pin hole 170 with the extending shape, and if the fixed frame part 100 rotates, the other side of the guide pin 340 slides along the guide pin hole 170 to guide the rotation of the fixed frame part 100.

The guide pin holes 170, the second through holes 311, and the guide pins 340 are provided plurally to prevent excessive loads from being applied to the guide pins 340 for guiding the rotation of the fixed frame part 100, thereby avoiding the guide pins 340 from being damaged or broken.

As described above, the sliding bracket device for the guide motor according to the present invention is configured to allow the slide frame part to slide on the fixed frame part so that the guide motor disposed on top of the slide frame part is selectively located inside and outside the boat according to the sliding directions of the slide frame part.

According to the present invention, further, if the slide frame part slides in one side direction thereof, the guide motor is located inside the boat, so that when the boat moves, there are no parts protruding from the boat, thereby making it easy to operate the boat.

According to the present invention, moreover, if the slide frame part slides in the other side direction thereof, the guide motor is located outside the boat, so that the guide motor operates in the state of protruding outward from the boat.

According to the present invention, in addition, the slide frame part includes the pair of guide members extending in the direction toward the fixed frame part, and the fixed frame part includes the guide rollers rotatable around the shafts to thus guide the guide members, so that the guide rollers of the fixed frame part serve to guide the sliding movement of the slide frame part.

According to the present invention, further, each guide member has the shape of the rod with the circular section, and the guide rollers whose surfaces coming into contact with the guide members may have the corresponding shapes to the shapes of the guide members, so that the guide rollers rotate by means of the sliding movements of the guide members in the state of inserting portions of the guide members thereinto, thereby guiding the sliding movements of the guide members.

According to the present invention, also, the slide frame part includes the connection members adapted to connect the guide members to each other, and the connection members have the stoppers adapted to limit the sliding distances of the slide frame part during the sliding movements of the slide frame part, so that the slide frame part can be prevented from being damaged and broken due to its excessive sliding movements, thereby improving its durability.

According to the present invention, moreover, each guide member has one or more slide fixing grooves formed thereon in the longitudinal direction thereof, and the fixed frame part has the slide fixing pins inserted into the through holes of the extension portions and the slide fixing grooves, so that if the slide fixing pins are inserted into the through holes and the slide fixing grooves after the slide frame part slides, the slide frame part becomes fixed in position.

According to the present invention, in addition, the slide fixing pins for fixing the slide frame part in position apply the elastic forces in the directions where the through holes and the slide fixing grooves are formed, and if the through holes and the slide fixing grooves are concentric with each other according to the sliding movements of the guide members, the slide fixing pins are automatically inserted into the through holes and the slide fixing grooves, thereby preventing the slide frame part from sliding.

According to the present invention, moreover, the sliding bracket device includes the rotation part disposed between the bow or stern of the boat and the fixed frame part to allow the fixed frame part to be rotatable with respect to the bow or stern of the boat, so that the rotation part rotates the guide motor in position in the state where the slide frame part slides to cause the guide motor to be located outside the boat.

According to the present invention, further, the rotation part, which is configured to rotate the guide motor in position, includes the rotation fixing pin adapted to pass through the fixed frame part and the fixed plate, so that in the state where the guide motor rotates in position, the rotation fixing pin passes through the fixed frame part and the fixed plate to fix the guide motor in position.

According to the present invention, additionally, the fixed frame part includes one or more guide pin holes extending in the circumferential direction with respect to the position where the other side of the rotating shaft is located, the fixed plate includes the plurality of second through holes formed at the positions corresponding to the guide pin holes, and the rotation part includes the guide pins inserted into the guide pin holes and the second through holes so that upon the rotation of the fixed frame part, the guide pins guide the rotation of the fixed frame part.

The present invention may be modified in various ways and may have several exemplary embodiments.
